  • Abstract
    The field emission current density j from the ternary alloy AlxGa1-xN is calculated as a function of a stoichiometric composition x for 0≤x≤1. In addition to the doping, the internal field emission is considered to contribute to the carrier concentration n of the conduction band of AlxGa1-xN. A full calculation is made to obtain the exact j from AlxGa1-xN as a function of x and the field F. Then we found the stoichiometric dependence of field emission from AlxGa1-xN by analyzing the effects of both the electron affinity and the carrier concentration.
